.In carrying out these objects the present invention provides-a novelmagazine construction which is adapted "to be mounted on' a' firearm,preferably in a recess formed in the firearm, which magazine includes ahousing preferably having. an'outer surface to conform or blend into theouter contour of the firearm. The magazine is held in position by ayieldable detent whichcan permit the rnag'a zine tobe quickly insertedand replaced with a minimum of efr'ort'. n n 7 safety feature in that itwill yield under undue pressures The construction also provides a inthefirearm and vent the firearm to relieve the pres- Themagazine of thepresent invention is "simplein. construction and comprises a rotarycarrier mounted in a bore in the housing and provided on its surfacewith longi-- tudinally extending recessesfor supporting and retainingcartridges forfsolely rotation therewith whereby jamming due to slidingaction of the cartridges in the magazine is eliminated. The housingwhich-encloses the carrier is i preferably provided with a singlelongitudinally extending opening which faces the firearm, when themagazine is in position thereon, and has guide means adjacent theopening for supporting a cartridge in aready position in which it can bedelivered to; the firing chamber of the fireai'rr'r.

i A-feature of the invention resides in the fact thatthe guide' meansis-preferably in the form of longitudinal ribs loeatedon each side ofthe opening and has a'space there between for receiving the cartridgefrom the carrier and has means for holding the cartridge against lateralmovement therefrom so that the magazine can bepre loaded.

The rilis, however, arejprovided with means whereby the 1 cartridge canbe released therefrom by longitudinal movement of the cartridgetherealong as it is fed to the firing chamber.

Another feature ofthe invention resides in the fact that the magazine"may accommodate rim-type cartridges by being provided with acounterbore' adjacent the end of the carrier into which the rims maypass so that the cartridge lies flat in' the carrier and can be readilycon trolled in its rotary movement with the carrier. 7

A still further feature of the present invention resides in thesimplicity of the construction of the magazine which enables it to bereadily manufactured and assembled at a relatively low cost. i

.Other'features and advantagesof the invention will be apparent from thespecification and claims when considered in connection with theaccompanying drawings in which:

The rotary magazine of the present invention has particular useinhandheld firearms such as pistols and rifles to supply a'plurality ofcartridges thereto and can be mounted thereon in various locations asmay be practical and convenient.

In the herein illustrated form of the invention a magaz'ine 10 isinserted in a recess 11 provided in'the frame 12 of a' 22 caliberpistolof the typedisclosed in my Patent No. 2,899,767 havingabarrel 13'disposed in a lower position on the frame. The magazine, which ispositioned above the barrelof the pistol, is designed to supply a largenumber of "cartridges thereto. As shown in FIG. 2, the recess 11 opensinto'a transfer chamber 12a within the frame of the pistol-adjacent thefiring chamber =14 formed in-"the barrel 13 which is closed by a slidingbreechblock 15 which carries the usual extractor and ejec- In accordancewith the preferred formof the invention; the magazine comprises-ahousing 16 having a cartridge carrier 17 'rotatably mounted therein. Themagazine is held m the recessby a detent means herein illustrated as aspring-pressed ball 18c arriedby the frame 12 of the,

pistol and engaging an aperture orrecess-1'9in the end of the magazine.This permits the magazineto be readily inserted and removed from thepistol and also provides a safety factor in that it permits the magazineto move outwardly upon building up of abnormal pressure in the shaped toprovide a camming action to assist the deflector rotation of the carrierto slightly more than one r'evolutioh, the slight excess beingsufiicient to cause the pusher to move thelast cartridge into readyposition.

Further, the meansfor limiting the rotation of the carrier may includeamanually operable means wherebythe-carrier "can be rotated against theurging means to without themaga'zine interfering with its use, andwithout transfer area",-whereby said area is vented to reduce thepressure. r

While the magazine" maytake various shapes, it is preferred to have'thehousing shaped "or contoured to blend with the" surface of the firearmadjacent the recess. In the herein illustrated form ofthe inven'tion-thehousing hasa curved outersu'rfacewhich, as shown in FIGS. 1 and 2,blends into the contour of the firearm to provide aconstruction which isbalanced, can bereadily handled interference in and S I I The housing asherein illustrated comprises, a cylindrical the-sighting-of the pistolby-the sights S member 20 forming side walls and a pair of'en'd walls j21, 22. The housing ispr'ovided with a longitudinal-bore 23 therein.While the housing may be fabricated in many ways, it is at presentpreferred to form the end wall 21 integral with the side walls 20 toprovide a casing and to form the end wall 22 as a separate member to beinserted into position to close the casing and be pinned in place tofacilitate-the assembly as will be explained.

The end walls 21, 22 are provided with aligned apertures 24, 25 whichform bearings for rotatably mounting a shaft 26 secured to the carrier17. One end 26a of the shaft 26 projects beyond the end wall 21 and theother end of the shaft is carried by the aperture 25 in a sleeve 27forming a continuation of the aperture 19 in the end wall 22 so that thecarrier is mounted coaxially with the bore in the housing as shown inFIGS. 2 and 3.

On the surface of the carrier are a plurality of longitudinallyextending cartridge-receiving recesses 28, herein illustrated as beingten in number. The recesses are so spaced with respect to the wall 20 ofthe bore 23 of the housing that cartridges 29 received in the recesseswill be retained therein for solely rotating movement with the carrierby said wall.

If it is desired to have the magazine accommodate cartridges having rims29a, the bore of the housing can be counterbored at 23a adjacent the endof the carrier to permit the rims to ride therein while the cartridge issupported in the recess.

In accordance with the preferred form of the invention, the housing hasa single elongate opening 30 in the side wall through which thecartridges pass into and out of the magazine. This opening, as shown inFIGS. 2 and 3, is in that portion of the side wall adapted to face thefirearm so that the magazine is completely closed to foreign matter whenin position on the firearm.

As herein illustrated, guide means is provided on the magazine forguiding the cartridges laterally from the carrier into a ready positionin which the sliding breechblock 15, as it moves to close the firingchamber 14, will move the cartridge into the firing chamber.

While the guide means may take many forms, in the herein illustratedform of the invention it comprises a pair of ribs 31, 32 each located ona side of the opening to project therefrom and receive the cartridgestherebetween as they are fed from the carrier. The carrier is normallyurged to rotate in the direction of the arrow A in FIGS. 3 and 7 todeliver the cartridges carried thereby seriatim to the guide means.While this rotating means may take many forms, in the illustrated formof the invention this means comprises a helical spring 33 having one end33a secured to the carrier and the other end 33b secured to theremovable end plate 22. Preferably, the spring surrounds the sleeve 27and an aligned boss 34 on the carrier and is supported thereby.

In order to deflect the cartridges from the recesses into the spacebetween the ribs in response to the rotation of the carrier, the presentinvention provides an annular groove 35 in the surface of the carrierintermediate the ends of the recesses and provides a deflecting finger36 on the housing at the far edge of the opening 30 projecting into thegroove so that as the cartridges are moved by the carrier into aposition overlying the opening the defleeting finger will cause them tomove laterally and into the opening and into said space between theribs. To facilitate this lateral movement, the trailing edge 28a of eachof the recesses is curved or shaped as shown in FIG. 3 to cooperate withthe cartridge engaging the defleeting member in a manner that continuedrotation of the carrier will cause'the cartridge to be moved laterallyaway from the carrier and out of the recess. As herein illustrated inFIG. 7, as the first cartridge is moved laterally, the carrier will movethe next cartridge into position behind the first cartridge and pushsaid first cartridge into the space between the ribs at the rear endthereof. The ribs, adjacent the rear end thereof, are provided with lips40 which engage the cartridge and hold it against further lateralmovement and in a ready position in which the lower edge of thecartridge is disposed to be engaged by the sliding breechblock 15. Itwill be supported on the breechblock as shown in FIG. 6 and when thebreechblock moves rearwardly to Withdraw and eject the spent cartridgecasing, the rim will drop to a position to be engaged by the breechblockand fed forwardly toward the firing chamber. The cartridges so held bythe guide means will prevent further rotation of the carrier under theurging of the spring until the first cartridge has been moved from readyposition. When this is accomplished, the carrier 17 again rotates tofeed the next cartridge to the opening.

In order to move the last cartridge in the magazine to ready position,the magazine of the present invention is provided with a pusher member41 which is carried by a wire bail 42 pivotally mounted on the carrierfor relative movement with respect to the carrier. The pusher memberlies in the last recess on the carrier and when the carrier has fed thelast cartridge into the opening, con- 7 tinued rotation of the carrierwill cause the pusher member to move into the opening as shown in FIG. 3so as to apply pressure to the last cartridge and maintain it in theready position in the guide means. Preferably the pusher has a conicalend 41a which will cause it to retract in the event that it isinadvertently engaged by the sliding breechblock. 7

. In order for the pusher to accomplish this, it will be seen that thecarrier must rotate through slightly more than one revolution. In theherein illustrated form of the invention, the means for controlling therotation of the carrier for slightly more than 360 comprises an arm 43rotatably mounted on the end 26a of the shaft extending through the endwall 21. The arm 43 has a stop pin 44 passing through the arm so as tohave ends 44a, 44b

-- projecting from the faces of the arm. The end 44a of the stop pincooperates with a slot 45 in the end plate 21 and limits the movement ofthe arm to a relatively small arc. A stop arm 46 is fixed to the end 26aof the shaft and projects outwardly to engage the other end 44b of thestop pin so that the rotation of the shaft 26 will be limited,

under the action of the spring, to a complete revolution of the shaftplus the amount of rotation permitted by the slot 45 in the end diskthrough its cooperation with the arm 43 and stop pin 44.

' 1 pusher.

The cartridge in the guide means is adapted to be moved longitudinallyof the ribs by the sliding breechblock and fed to the firing chamber.The forward ends of the ribs 31, 32, as shown in FIGS. 6 to 8, aredevoid of the lips 40 so that the cartridge, as it moves longitudinallyof the ribs, is freed from any retaining action of the lips and can bereleased from the magazine. Preferably, the forward ends of the ribmembers are provided with downwardly deflecting cams 47, 48 for guidingthe nose and rim of the cartridge downwardly, as shown in the dot anddash lines in FIG. 7, into position to move into the firing chamber ofthe pistol.

The stop arm 46 can also function as the means for rotating the carrier17 in a reverse direction against the action of the helical spring whenit is desired to load the magazine. In this case, with the magazinereleased from the pistol, cartridges are fed longitudinally of the guideribs into position in which they overlie the opening in the housing. Thecartridges are then fed through the opening, the first cartridge lyingin the recess adjacent the The carrier is then rotated against theaction of thespring by the arm 46 to bring the next recess in line withthe opening and the next cartridge is deposited in the recess. Thiscontinues until all of the recesses, except the one carrying the pusher,are filled with cartridges and the last cartridge is then inserted intoready position in the ribs and will be held in this position by the lipsand the pressure of the cartridge at the opening. Thus, the magazinewill hold ten cartridges. Since the magazines can be preloaded, one mayhave a supply of magazines on hand and quickly and easily interchangethem with the pistol to provide for a rapid fire operation of thepistol.

The magazine of the present invention is simple to construct and easy toassemble. As shown in the drawings,

the cylindrical member 20 forming the side walls and the end wallzl areformed integral. The ribs '31, 32 are secured to the cylindrical memberto project therefrom and form, a casing unit. The shaft 26 which has thearm 43 and stop arm 46 mounted thereon is inserted'throughtheaperture-24- inthe wall 21. The carrier 17 is positioned on the'shaftand is pinned thereto by pin 49. The torsion spring isput in positionand has one end secured to the carrier, and the other end secured \tothe end plate 22, and

end 26b of the shaft is inserted in the bearing aperture I in sleeve 27on the end plate 22. The end plate is rotated sufiiciently totension'the torsion spring and is then inserted into the end of thecasing and pinned in position by pin '50 or any suitable securing means,completing the magazine assembly.

, Thus, it will be apparent'that ithe'elements which can be readilymachined or otherwise formed and assembled will very economicallyproduce magazines for use with firearms.

Further, itwill be noted that inasmuch as the movement of the cartridgein the magazine is solely a rotary move- .ment and there isnolongitudinal sliding movement as might wipe ofi wax from thecartridges or lead from the 'usual lead-nose of the cartridgethat thebuilding up, particularly in cold weather, of obstacles to the movementof the cartridge is substantially eliminated, and a smoothworking,effective cartridge supply is provided for the firearm. Variations andmodifications may be made within the scope of the claims and portions ofthe improvements may be used without others.
